    Hello, Please ask a question about ELM822 Datasheet

  • # Example questions: ➢ The datasheet includes several graphs showing 'isink-vout' and 'isource-vout' at different vdd levels. what do these graphs indicate about the output drive capability of the amplifier?
    ➢ How does increasing the supply voltage (vdd) generally affect the common mode rejection ratio (cmrr)?
    ➢ What is the approximate maximum output voltage (vout) achievable with a 10kω load when the supply voltage (vdd) is 5v?

    Datasheet Summary with AI

    Okay, I'm summarizing the information from the provided document. This is a datasheet for the ELM822xA operational amplifier.

    Key Features and Specifications:

    ️· Technology: CMOS
    ️· Supply Voltage: (Vdd) Typically operating between 1.2V to 6.0V.
    ️· Quiescent Current: Very low (implied to be in the microampere range; specific value not directly stated, but a key selling point).
    ️· Input Offset Voltage: (Not directly stated, but likely low given the technology.)
    ️· Gain-Bandwidth Product: (Not directly stated, but will vary with supply voltage)
    ️· Slew Rate: Varies with supply voltage (graphs included). Around 2.0 V/μs at Vdd=1.5V.
    ️· Short Circuit Current: Increases with Vdd.
    ️· Maximum/Minimum Output Voltage (Vout): Depend on the load resistor (RL) and supply voltage (Vdd). Graphs provided to illustrate.
    ️· Pulse Response: Provided for Vdd=1.5V and Vdd=3.0V.
